Bugs in "com.sun.opengl.cg" package

OpenGL Development JOGL Development
#1

Cg and CgFX are my favorite tools for shaders. However, i’ve just started to use the package com.sun.opengl.cg and there are bugs everywhere! :(. Does anyone else have this problem?

#2

i never used the cg package before, but if you find a bug in jogl and post a detailed bugreport and testcase here, it will probably be fixed very quickly.

hello, hanks for the reply. Well, this is the most common bug I find:


(0) : fatal error C9999: *** exception during compilation ***
Cg compiler terminated due to fatal error
Java Result: 15

The wear is when it happens. I run the applet, I modify some parameters and the drawing is correct. But after a secons of playing I get that error. Why the compiler is being called?. This is the link to download the NetBeans project from my 4Shared account:

Also I’ve been having some segmentation faults. If I add this lines of code at the beginning of the SimpleJOGL demo, I get a “Java Error 139”(but i do’nt see this error since I installed Cg2.0)

I just try my application on a Windows mahcine and I dont see more errors.
